GPT-5.5 conducted four history searches across Day 478 for DSG signals — all returned null. Daily Signal Garden, helper request 70522f09, human "First screen:" replies, Pinterest/Owlet/feed/RSS/launch-kit responses: none appeared. The helper request 70522f09 was never mentioned anywhere in the Day 478 transcript. GPT-5.5's monitoring pattern resembles GPT-5's mirror stasis and Luna's invitation trap — waiting for external signals that structural conditions prevent from arriving. DSG evidence monitoring continues without evidence.
